Radiotherapy apparatus for animal

Abstract

A radiotherapy apparatus for an animal comprises a treatment part including an accommodation space for placing an animal, an irradiation part including an electron generator and a linear accelerator coupled to one side of the electron generator and disposed in a direction perpendicular to the treatment part, the linear accelerator being configured to emit radiation toward the treatment part, and an image acquisition part located at a preset interval from the treatment part along an irradiation direction of the radiation and configured to obtain an image of an irradiation area when the radiation is applied, wherein the radiation has an output of 1 MeV to 2 MeV so as to be applied to a diseased part located within a predetermined distance range from epidermis of the animal.

The invention claimed is: 
     
       1. A radiotherapy apparatus for an animal, comprising:
 a treatment part including an accommodation space for placing an animal; 
 an irradiation part including an electron generator and a linear accelerator coupled to one side of the electron generator and disposed in a direction perpendicular to the treatment part, the linear accelerator being configured to emit radiation toward the treatment part; and 
 an image acquisition part located at a preset interval from the treatment part along an irradiation direction of the radiation and configured to obtain an image of an irradiation area when the radiation is applied, 
 a beam stopper located to be spaced apart from the image acquisition part along the irradiation direction of the radiation to interrupt leakage of the radiation through at least one of the treatment part or the image acquisition part, 
 wherein the radiation has an output of 1 MeV to 2 MeV so as to be applied to a diseased part located within a predetermined distance range from epidermis of the animal, 
 the irradiation part, the treatment part, the image acquisition part, and the beam stopper are located in said order along the irradiation direction of radiation, 
 the irradiation part further includes a first collimator and a second collimator configured to adjust the irradiation area of the radiation, 
 the first collimator is a multi-leaf collimator, and 
 the second collimator is a pin-hole collimator. 
 
     
     
       2. The radiotherapy apparatus of  claim 1 , wherein the irradiation part further includes a lamp configured to identify the irradiation area when the irradiation is applied and an ion chamber configured to measure an output of the radiation, and
 wherein the lamp and the ion chamber are located on the same plane. 
 
     
     
       3. The radiotherapy apparatus of  claim 1 , wherein the treatment part is movable in a horizontal direction and a vertical direction with respect to a parallel surface of the ground. 
     
     
       4. The radiotherapy apparatus of  claim 1 , wherein the predetermined distance range is a range of 10 cm to 20 cm. 
     
     
       5. The radiotherapy apparatus of  claim 1 , wherein the first collimator determines a radiation range of the radiation, and the second collimator sets a magnitude of the radiation. 
     
     
       6. The radiotherapy apparatus of  claim 1 , comprising:
 an error correction device to correct a position of one of the irradiation part, the image acquisition part and a combination thereof.
